plural corydoras

: any of a genus (Corydoras of the family Callichthyidae) of chiefly tropical South American catfish that are usually 1 ½ to 3 inches (3.8 to 7.6 centimeters) in length and include some (such as C. aeneus, C. metae, and C. paleatus) kept in aquariums

Word History

Etymology

borrowed from New Latin, genus name, from Greek kóry "helmet" (probably of pre-Greek substratal origin) + New Latin -doras, perhaps erroneously for Greek thṓrax "breastplate, cuirass" — more at thorax

Note: The genus name Corydoras was introduced by the French naturalist Bernard Germain de Lacépède (1756-1825) in Histoire naturelle des poissons, tome cinquième (Paris, An XI [1803]), p. 147. Lacépède thus describes the naming: "Le nom générique par lequel nous avons cru devoir la distinguer, indique la cuirasse et le casque qu'elle a reçus de la nature¹ … [¹Corys, en grec, signifie casque; et doras cuirasse]" ("The genus name by which we have thought it [the fish] should be distinguished denotes the breastplate and helmet that it has received from nature¹ … [¹Corys, in Greek, means helmet, and doras breastplate].") Though Lacépède clearly meant to cite the Greek word for "breastplate," he gives instead a nonexistent word doras, perhaps having confused thṓrax "breastplate" with dorá "skin, hide." Though he cites the word for "helmet" correctly, the stem of kórys is koryth-, and the correct form in a compound would have been korytho-.
